Don't know whether your need for a headset is the same as the problem I had but ...
I needed a tapered headset for the on-one lurcher I had bought in their sale. I almost bought their smoothie mixer but then realised they wanted an extra £15 for the 1.5" crown race ... which made it almost £55 in total.

I've got a black Chris king tapered head set which is 1 year old off my second bike in need to remove to sell if your interested. Its had little use and is in great condition.
